BioMedical Life Systems, is proud to introduce it's new generation in Electro-Therapy Devices, the QuadStar Elite four channel up to 8 electrodes TENS, NMS, High-Volt and Interferential stimulator in one portable unit. It's compact size and user friendly programming features make the QuadStar Elite's design unique among Electro-Therapy Devices. The device has an easy to read LCD screen and a digital keypad. Simple to understand instructions guide the user through nine pre-programmed protocols and four types of waveforms; Symmetrical Biphasic Square Wave; Asymmetrical Biphasic Square Wave; Sine Wave; and Monophasic High-Volt, Twin Peak. The user can sequence two or more modalities for complete treatment. The device has a patient lock system that, when activated prevents the patient from changing any of the set parameters. When the Patient Lock Systems is turned off, a patient compliance meter is displayed showing how long the device was used. A timer allows the patient to use the device for a specified period of time. This device comes with all accessories, an internal rechargeable Nicad battery pack and wall adaptor.
